Question 22 • Physics

Which best summarizes Brandi’s statement about doing work while posing?

Answer
A
She did no work because she did not move the scales or sword while she posed.
B
She did more work using her right hand than her left because her right hand was higher.
C
She did work the entire time she posed because she was tired at the end.
D
She did no work because she did not exert any forces on objects.

Explanation

In physics, work is done when a force causes an object to move in the direction of that force. While Brandi posed, the scales and sword stayed still, so she did no mechanical work on them, even though holding them may have made her tired. This makes “She did no work because she did not move the scales or sword while she posed” the best summary.
